No one has ever denied that
the sun has an effect on climate.
I suspect that the barycentric movement of
the sun has an effect on the climate.
Not exact matches
«The result reverses understanding of solar cycle
climate effects,» which
had been that the
sun generally warms the
climate on the way up from minimum to maximum and generally cools the
climate on the way down from maximum to minimum, explains atmospheric scientist Piers Forster of the University of Leeds in England.
The total energy in these particles is insignificant compared to the energy in the form of light from the
sun, so the variation of the magnetic field will not
have a direct
effect on Earth
climate.
However, the
sun provides an abundant source of energy and by changing the earth's radiative balance so that we absorb a little more of that energy, we are
having an important
effect on the earth's
climate.
Sulphate aerosols
have a cooling
effect on the
climate because they scatter light from the
Sun, reflecting its energy back out into space.
The» top ten» arguments employed by the relatively few deniers with credentials in any aspect of
climate - change science (which arguments include «the
sun is doing it», «Earth's
climate was changing before there were people here», «
climate is changing
on Mars but there are no SUVs there», «the Earth hasn't been warming since 1998», «thermometer records showing heating are contaminated by the urban - heat - island
effect», «satellite measurements show cooling rather than warming»)
have all been shown in the serious scientific literature to be wrong or irrelevant, but explaining their defects requires at least a paragraph or two for each one.
If you look at Figure 5B in the recent paper by Foukal et al.
on Nature, where they claim the
Sun does not
have any
effect on climate, you will be able to see huge volcano spikes that really do not
have anything to do with the temperature data.
The take - away is that if the
Sun were now to stop all activity, as during the 16th - century Maunder Minimum, it
would produce an
effect on climate no greater than the next twenty years» worth of greenhouse gas emissions — some say, ten years.
Just as a hypothetical example: If
climate scientist will tell me that recent pause in global warming is due to the
effect of an inactive
sun (which is the reality as reported by following) http://www.spaceweather.com and that they will go back and improve their models to account for this, then I
would be more inclined to believe their other claims... Instead the IPCC doubles down
on their predictions and claim the future
effects will be worst than they originally thought?
From the beginning of this debate I
have argued that the
Sun has a much more powerful
effect on the
climate than anything we humans
have or will
have on our environment.
I also
have kept tract of the
Sun's cycles, as well as new discoveries about the
effect of solar winds, that are now part of the
effect on the Earth's
climate.
About the book: The
effect of the
sun's activity
on climate change
has been either scarcely known or overlooked.
My most trenchant critic was a distinguished solar scientist who felt that the
sun could not possibly
have such an
effect on the
climate system below.
What Fred Berple probably thought, was that Gavin's apparent comment that the
sun's
effect on climate was photo voltaic,
had comparable rigor to Gavin's other comments
on climate.
So, how do we know that the
sun has a large
effect on climate?
Dr. Curry
has referenced a work by Feulner G., Rahmstorf S. (2010), that uses a traditional
climate model to evaluate the
effect of the
sun on the
climate in the eventuality that a new prolonger sola minimum
would occur.
I can see Leif's objection to the idea that movement of the solar system barycentre
has a significant
effect on an object the size of the
sun but is it necessary to propose an
effect on the
sun for Earth's
climate purposes?
The climatic system / oceanic system are driven by the
sun, therefore it stands to reason any changes in solar output (variations) will
have an
effect on these two systems which in turn will
have an
effect on the
climate.
We
have been focused
on climate models rather than
on climate dynamics and theory that is needed to understand the
effects of the
sun on climate, the network of natural internal variability
on multiple time scales, the mathematics of extreme events, and the predictability of a complex system characterized by spatio - temporal chaos.
Perhaps a couple dozen people people should write several dozen papers studying what sort of direct and indirect
effects the
sun might
have on our
climate!
What about spectrum, did the
sun put out the same or different types of energy than today, more or less infra - red, visible, ultraviolet, xrays, and what
effect wuld that
have on climate?
One hypothesis why CO2
has no significant
effect on temperatures is that much of the Earth, particularly in the tropical oceanic areas which receive much of the energy from the
sun are regulated by emerging
climate phenomena, not CO2, and these are what primarily determine temperatures in these areas.
If verified, this
effect would represent a dramatic advance not only in the basic understanding of the
Sun's variable activity, but also in the potential influence of this variability
on the Earth's
climate.
We also
have projects in the general area of non-linear geophysics such as examining
climate feedbacks in the hydrological cycle and the
effects of a variable
sun on climate model simulations
